DOOR-CHECK.

SPECIFICATION forming part of Letters Patent No. 251,732, dated January3, 1882. l Appiicanon ined August 23, Iseo. (Model.)

' lowing is a full, clear, and exact description thereof', referencebeinghad to the accompanying drawings, and 'to the letters of referencemarked tlIereon,\vlIich form a part ot'this speciteation.

This invention relates to door-cl1ecks; and itconsists in the severalnovel features of construction hereinaiter set forth, and pointed outinthe claims.

The door-check herein described and claim ed operates not only to checkthe door slightly' open, as is common with door-checks, but it may alsobe made at will to hold the door from closing, and is adapted to fastenthe door closed.

In the accompanying drawings', Figure l is'` a perspective view ot'thecheck as it appears when the door is closed and when used to'fast enthe door in this position. Fig. 2 is a perspective view of the door opento the length of the eheck-link. Fig. 3 shows the check-link pendent onthe door-frame. Fig. 4 is a central horizontal section ot' the completedevice in the position shown in Fig. 1. Fig. 5 is a central horizontalsection of the parts applied to the door, and ot the outer end of thelink when the door is ajar and is held from movement in eitherdirection. Figs.4 6, 7, 8, 9, and l0 are detail views.

A is the door, and B is the door-frame.

C is a metal casing, about half an inch deep, containing the mechanismpermanently applied to the door.

C is a boss applied to the frame B, hush with the case C, and having thecheck-link L,

y pivoted thereto by means of a hook, E', on the `boss and eye e on thelink. Thelink L is slotted at S, and engages the door by means ofaturnpin, T, secured to the door by means of the case C. An especiallynovel feature inthe turnpin T is that it may he slid backward andforward to and from the edge of the door in the slot'D of the case Cwith a movement over the corner or front edge of the case C, so as toserve, when at the door-edge, as a T, by which to hold the cheek-linkand arrest the door, and tv hen slid inward away from the door-edge toserve as a turnfpin fastening, adapted to hold the check-link againstthe case C, and thus secure the door closed. To these ends said turn-pinis of peculiar construction, which will be pres ently explained.`

I is a horizontally-sliding catch, held loosely in place on the door bythe case C, beneath which it is centrally placed. Its inner and exposedend is upturned to afford hold for the thumb and 4Iinger for the purposeot' Working it, as seen clearly` in Figs. 2, 4, and 5, and its throw islimited by the screwj, which passes through the slot i in the slide.Said slide is intended to engage with the notch N in the link L when thedoor is opened the length of the check-link, and operates to hold thedoor `from closing. The notch N is clearly shown in Figs. 3,4, and 5,and in the last figure mentioned the slide l is engaged with said notch,as described. The slide I also serves' as a bottom plate, on which theturn-pin T runs, and ithas arib, r, on its outer face, which tits in agroove, g, on the under face of the turn-pin, which rib, so far as itextends in the movement of the turn-pin, holds the latter from rotation.The turn-pin T consists of the external thumb-head, the standard orshank t2, the lateral arms t, and the rear projection, t. The slot D ofthe case C, in which the shank t2 runs, extends down the front face ofthe case, as shown in Fig. 10, so that the turn-pin may tilt into theposition shown in Figs. 2 and 5. When it so tilts the projection tprotrudes from the slot D, as shown in said figures, and by suchprotrnsion holds the turn-pin from rotation at this point. rotationuntil moved to the rear of the slot D, where it is clear of the rib, andmay turn in order to be released from the check-link L. If, however, itis desired to lock the turnpin at this point to prevent its turning(aswhen the turn-pin is used to hold the link L as a Jfasten- The rib rsimilarly holds it from ing of the closed door,) it can be so locked by9 pushing in the slide I, so that the lugs b b, cast on the slide, passone to each side ot' the rear projection, t', of the turn-pin andprevent its rotation. The link L is provided With a projecting corner,a, which, when the linkis thrown IOC off the turn-pin and falls pendentfrom the hook El, sets up under said hook and prevents the link fromswinging outward in the way of the door.

The boss C is of peculiar construction. It consists of the hollow risingpart, tapering toward the top, and the cap-plate o. The hook E is castas an extension on the inner wall of the boss, and, as it overhangs theaperture of the shell, draws readily from the sand. The

cap a at its inner edge sets up against the hook E', and has a smallflange, c2, on its under face, which drops close inside the outer wallofthe boss', as seen in Fig. 4. The link being tirst ap plied to thehook E', the cap c is inserted be-` neath the hook. The parts are thenfastened to the door-frame by screws passing inward through the cap c',as shown, and all the parts v are thus held permanently in place on thedoor' frame.

It has been found that by reason of the lnold- Ying usually present onthe frames of doors itv is necessary to pivot the lilik to a raised partor boss, and to correspondingly elevate the T'fastening on the door.When this is done a stationary T-piece to engage the link projects sofar as to be seriously in the way. This fault; is remedied in theconstruction herein shown,

'wherein the turn-pin is at the edge of the door thus engaged, inwardlyfrom and outwardly to the edge of the door, so as to co-operate with thebar Lto cheek the door when fijar, and to form therewith a fastening tothe closed door, substantially as described.

2. In combination with arigid check link or bar, L, having a notch orshoulder, N, and a suitable catch, T, ou the door, arranged to engagewitli said link or bar to check the door ajar, the sliding latch I,adapted to be engaged at will with the shoulder N ofthe link L, so as tohold the door from closing, substantially as described.

3. In combination with the slotted link or bar L, the turn-pin T,secured inovably to the door by means which permit the turn-pin to slideinward from and outward to the edge of the door, and to rotate toreceive or release the link only when receded, substantially asdescribed.

4. In adoor-check, the slotted link L, pivoted to the boss C on thedoor-frame, the case C, having the slot D, the turn-pin T, havingprojections t and t and the groove g, and the bottom plate, I, providedwith the rib r, combined and operating substantially as described.

5. In combination, the slotted link L, pivoted to the door-frame, theretaining-case G on the door, the rotating turn-pin T, held by the caseC, and slide I, having the lugs b b, whereby the turn-pin may be securedfrom rotation when operating with the link L asa fastening for theclosed door, substantially as described.

6. The link L pivoted to the door-frame by the hooky E and eye e, andconstructed with the corner-projectionsa,which bear against the hook Eto prevent the link from swinging in the way of the door, substantiallyas described.

In testimony that I claim the foregoingas my invention I aftx mysignature in presence of two witnesses.
